I would leave this one out. It gives the false impression that ibook1
works ok, while later it will likely eat your filesystem. Its not a
regression in that sense because 2.6.15 was also broken and noone
complained.

Ben H and I agree that the fix makes sense and is correct and should
go in for 2.6.16.  Your iBook crashes are a separate problem.
